some questions
 

hey i just got my 1986 rx7 about a week and a half ago, and i was wondering if i could just buy an aftermarket turbo kit and put it on my non turbo rx or would i have to replace the intake manifold

if you search for "turbo NA" you will get about a million threads. only read the threads that are more than 2 pages(to insure that your getting something worth reading) . that will answer your question, and then some, and it will also keep you reading for the next few days.... this question is asked a ridicules number of times every week.
